Abstract
Significant WAAS Advancements in 2006 Track: New Technology and System Integration Author(s): Eric Gakstatter Wide Area Augmentation System (WAAS) has quickly emerged as a significant source of accurate GPS corrections for mapping-grade work. 2006 is one of the most important years for WAAS in the GIS community. Two more broadcasting satellites will become available, and 13 new ground stations will come online to enhance the WAAS service area in North America. This is an in-depth look at WAAS from a GIS perspective including the benefits, drawbacks, and 'gotchas.' Particular attention will be paid to WAAS satellite visibility and reliability as well as GPS receiver performance comparisons with USCG beacon and postprocess differential correction. As a practical example of applying WAAS-corrected data, the author will present how ArcPad was used in the construction layout, construction monitoring, and as-built production of an 18-hole golf course.
